What if Williams wins the Super Rugby title in a few weeks time, a second NRL title, a few tests for the Kiwis, returns to bag a second Rugby World Cup as a senior All Black and knocks out a few boxers along the way?

Only time will tell, but it would be a near-unrivalled legacy.

And for those wondering why the NZRU has sent him off with a friendly hug, isn't it obvious?

He's been a walking publicity machine for rugby union since he arrived in Christchurch.

And as a bonus he's played the house down.

If he comes back, the NZRU is in a position to simply turn the tap back on. Why would it jeopardise that now?

Their only real concern is that many of us, probably plenty of the knockers included, will be tuning in to a few Roosters matches next season.
